This is a multilateration library implemented in Rust, which is loosly based on Java trilateration library.

Details

• It exposes one function that uses a vector of Measurement struct as an input. Output will be the tuple struct called Point which contains the output coordinates as a vector in the first tuple slot

  use multilateration::{multilaterate, Measurement, Point};
  
  fn main() -> Result<()> {
    let measurements = vec![
      Measurement::new(Point(vec![1.0, 1.0, 1.0]), 1.0),
      Measurement::new(Point(vec![3.0, 1.0, 1.0]), 1.0),
      Measurement::new(Point(vec![2.0, 2.0, 1.0]), 1.0),
    ];
  
    let coordinates = multilaterate(measurements).unwrap().0;
    println!("Coordinates are: {:?}", coordinates);
    Ok(())
  }
  

  Coordinates are: [2.0, 1.0000157132198315, 0.9943941804736127]
  

Error conditions

• Points have different dimensions

  use multilateration::{multilaterate, Measurement, Point};

  fn main() -> Result<()> {
    let measurements = vec![
      Measurement::new(Point(vec![1.0, 1.0]), 1.0),
      Measurement::new(Point(vec![3.0, 1.0, 1.0]), 1.0),
      Measurement::new(Point(vec![2.0, 2.0, 1.0]), 1.0),
    ];

    let result = multilaterate(measurements);
    println!("Result is: {:?}", result);
    Ok(())
  }

Result is: Err(All points must have the same dimensions)

• Points have no dimensions

  use multilateration::{multilaterate, Measurement, Point};

  fn main() -> Result<()> {
    let measurements = vec![
      Measurement::new(Point(vec![]), 1.0),
      Measurement::new(Point(vec![]), 1.0),
      Measurement::new(Point(vec![]), 1.0),
    ];

    let result = multilaterate(measurements);
    println!("Result is: {:?}", result);
    Ok(())
  }

Result is: Err(Points must contain at least one dimension)
